Abstract
A detailed NMR and MS analysis of α-onocerin was performed in
order to provide precise phytochemical reference for structure identification
and quality control of this analytical lead compound from
Ononis spinosa the roots of which are widely used as a diuretic drug.
Unambiguous 1H- and 13C-NMR assignments revealed that
the linkage of two subunits were confirmed to possess identical stereochemistries
in this triterpenoid.
